As a patch, the new version doesn’t have new features for end users. It mostly fixes issues:

An important security fix. The problem was that hackers could gain access to your administration panel, if they knew your admin URL. Multi-Vendor had a similar issue: a vendor could create an admin account and gain partial access to your admin panel. Both vulnerabilities are present in CS-Cart and Multi-Vendor 4.0.1—4.3.8. We strongly recommend that you upgrade to 4.3.9 ASAP to seal those security flaws. We’ve also sent emails to all CS-Cart and Multi-Vendor license owners. Check your mailboxes now. Those emails contain instructions on how to eliminate the vulnerability.

PayPal partial refund works fine. Previously, when an admin changed the return request status for orders with multiple products, PayPal partial refund could be performed multiple times. It meant that one of the products in the order could be refunded over and over again. Now, the refund process works correctly.

The payment processor response for PayPal payments changes properly. A payment processor response notifies you of events related to transactions. You can see the response status on the order details page in the admin panel. Previously, when the payment processor received IPN in PayPal Express Checkout, the processor response wasn’t actualized. An admin had to manually check payment status for every order. Now, this issue is fixed and the response is actualized when IPN is received.

Taxes based on Unit price are calculated correctly for unauthorized users. Before, when a guest customer placed an order, the product prices at checkout and in the cart could be displayed without taxes. We fixed the calculation process and now taxes are correctly applied to all products for both authorized users and guests.

Tracking number is always displayed for a customer. Before the fix, a customer couldn’t see the tracking number on the order details page, if you didn’t specified a carrier for that order. Now, tracking number is always displayed for customers whether you specified the carrier in the admin panel or not.

The HiDPI displays support add-on doesn’t shrink product images, when you clone products. The add-on influenced the cloning process of products: when you cloned a product, the size of its image decreased twice with each new cloning. We’ve fixed the issue and now the size of images of the cloned products stays the same.

See what hooks we’ve added and what else we’ve fixed in the changelog.

Let’s assume you want to start your own company, or that you already have one, and the next step towards advancement is creating a website. What should you do? Well, you can either take a quick online course or a tutorial on how to make one, or hire a web designer to do it for you. After all it’s in your best interest that your online store, blog, or company website look really attractive and professional. However sooner or later the issue known as web hosting will come up, and people will start to ask you about which web hosting service company you are going to choose as your provider.

If you have never created a website and are relatively new to the whole thing, you might ask: “What is web hosting, and how does it affect my website?” Well, web hosting is very important for a website’s performance and its speed. For example, you can create an eCommerce website using a fast CS-Cart software as your platform, but the speed of your CS-Cart store will also depend on web hosting. If the hosting is not that good and fast—a page will still take much time to load and the user will probably leave and won’t even give your content a chance.

It’s basically a server where your website is located and depending on user proximity to that server its loading speed is either fast or slow. So, a good web hosting service should have numerous servers where your content is uploaded, so that all of the users around the world have a satisfying experience when browsing your website.

There are many more features and details related to choosing a web hosting service, and for someone who is a first time user, all of this can be really puzzling. Luckily, First Site Guide has designed an infographic that will show you everything you need to know about web hosting. Once you are well-informed it’s far easier to make the right decision and choose a provider that will meet your demands and goals. Once you are done, you will know what web hosting is, what a good provider should provide and the existing types of web hosting.
